MOTOR-POWERED ARTICULATABLE SURGICAL INSTRUMENTS

摘要

A motor driven surgical instrument that includes a surgical end effector configured to perform at least one surgical procedure in response to firing motions applied thereto from a firing system. The surgical instrument further includes an articulation system that is configured to facilitate articulation of the end effector relative to an elongated tool axis. The instrument further includes a coupler assembly configured to enable the motor to selectively power the firing system and the articulation system.

1. A surgical instrument comprising:
an elongated shaft assembly defining a longitudinal tool axis; a surgical end effector operably coupled to the elongated shaft assembly for selective articulation relative thereto, the surgical end effector being configured to perform at least one surgical procedure in response to firing motions applied thereto; an articulation system operably interfacing with the elongated shaft assembly for applying articulation motions to the surgical end effector; a firing member assembly operably interfacing with the elongated shaft assembly to apply the firing motions to the surgical end effector; a motor configured to generate rotary actuation motions; and a drive coupler assembly interfacing with the motor and the articulation system such that when the drive coupler assembly is in a first configuration, operation of the motor will result in the application of the actuation motions to the articulation system resulting in articulation of the surgical end effector relative to the longitudinal tool axis and when the drive coupler assembly is in a second configuration, operation of the motor will result in the application of actuation motions to the firing member assembly causing the firing member assembly to apply at least one of the firing motions to the surgical end effector.
